The Lengshuiqing magmatic Ni-Cu ore deposit is hosted in four small mid-Neoproterozoic mafic-ultramafic intrusions in the western margin of the Yangtze craton in China. The ore-bearing intrusions were emplaced into early Neoproterozoic metamorphosed volcanic-sedimentary rocks, granites, and diorites. The intrusions are dominated by lherzolite, olivine websterite, websterite, and gabbro, with sulfide mineralization associated with ultramafic rocks in the lower parts of the intrusions. The forsterite contents of olivine crystals in the Lengshuiqing ore-bearing intrusions are up to 86 mol %, indicating that their parental magma experienced moderate degrees of fractional crystallization. Olivine crystals in the intrusions are depleted in Ca (
